Definitions
- the present invention relates to a device and method for producing frothy milk, as well as to a coffee machine comprising such a device and actuating such method.
- the invention relates to a device for frothing milk when preparing beverages containing frothy milk, such as cappuccino, latte and the like.
- the invention generally applies to liquid food adapted to be frothed.
- frothing is meant a process in which air is incorporated into a liquid, i.e. an emulsion of air is formed in the liquid, resulting in a fine dispersion of air bubbles in the frothy liquid.
- Devices for frothing and heating milk are commercially known; in fact, in order to generate frothy milk, the milk is heated generally by vapor injection.
- milk is placed in a container, a duct delivering vapor, known as “steam wand”, is immersed into the milk held in the container, thereby forming frothy milk; this method is generally used in commercial and HoReCa machines.
- EP 1501398 describes a coffee machine provided with a frothing device comprising a vapor input line and an air input line entering a T-shaped manifold, the latter having a delivering line extending therefrom to deliver a mixture of air and vapor.
- the air input line is connected to a source of pressurized air, in this case a compressor for adjusting the air flow.
- the compressor has to work at a delivery pressure greater than the vapor pressure, in order to be able to properly operate.
- the mixture of air and vapor obtained from the collector is directly delivered into a container where the held milk is heated and frothed.
- EP 2534986 describes a coffee machine provided with a frothing device in which pressurized air is fed to the service boiler, i.e. to the boiler generating vapor and heating the water needed for producing beverages. The air-vapor mixture is then conveyed to the delivering duct immersed in the milk in the respective container.
- a frothing device to froth beverages, particularly milk, able to overcome the above described problems, is therefore needed.
- Another object of the invention is to provide a device for heating and frothing milk, able to precisely adjust the frothing degree of the milk while maintaining maximum efficiency regardless of the required frothing degree of the milk.
- a further object of the invention is to provide a simple device for heating and frothing milk which can be easily cleaned.
- a frothing device to froth a beverage, particularly milk comprising: vapor producing means; pressurized-air producing means; air-vapor delivering means to deliver air and vapor to the beverage; characterized in that said vapor producing means and said pressurized-air producing means are connected to a tank for respectively feeding vapor and air to said tank, and in that said tank is connected to said air-vapor delivering means to deliver air and vapor to the beverage, that is to say to means frothing the milk.
- the tank is provided with a pressure sensor, this sensor being preferably a pressure transducer and/or a pressure switch.
- the pressure in the tank can be detected for example by measuring the speed and/or flow rate of air and/or vapor, and/or by means of the rotation speed of the air generating pump, etc.
- detect the pressure means herein a pressure measurement, for example by means of a sensor, and/or a pressure estimation based on measuring other operating parameters selected, for example, among speed, flow rate (or a combination thereof), of the air and/or vapor flow.
- the pressurized-air producing means comprise a pump connected to the tank through a duct, the latter being provided with at least one intercepting means to intercept the air flow, preferably a flow regulator and/or a non-return valve.
- the device comprises intercepting means arranged both on connecting ducts which connect vapor producing means to the tank and on connecting ducts which connect said tank to delivering means to deliver air and vapor to the milk (or other beverage).
- the intercepting means are electrovalves, possibly three-way electrovalves; advantageously, at least the electrovalve located on the duct that connects the vapor producing boiler to the mixing tank is a three-way electrovalve provided with a drain for removing condensed water which forms when the circuit is at rest.
- device of the present invention further comprises means to intercept the air flow, arranged between the air pump and the air-vapor mixing tank; such means may comprise at least one of a flow regulator and a non-return valve, or both of them.
- the device comprises a control unit connected to both the pressurized-air producing pump and the intercepting means, preferably electrovalves, that are on the duct feeding vapor to the tank.
- the control unit is further connected to both the pressure sensor and the electrovalve or to other intercepting means placed on the duct that feeds air-vapor to the delivering means to deliver air and vapor to the milk or other beverage.
- the pressure switch is set to a preset pressure value, at which a “pressure-reached” signal is generated.
- the pressure switch is connected to the control unit (CPU) and, as the target pressure is reached, the signal thereby generated is sent to the control unit.
- the signal may be generated by an on-off contact, the control unit, usually a CPU, receives the signal and opens the electrovalve.
- the pressure switch is connected in series with respect to the electrovalve for delivering mixture to the tank; when the operating pressure of the mixing tank is reached, the pressure switch closes the on-off contact and therefore this electrovalve is electrically activated.
- electrovalve is placed on the duct connecting the mixing tank with the delivering means (also known as “wand”), to deliver vapor and air to the milk or other beverage.
- At least one of said tank, said vapor intercepting means and said intercepting means to intercept the air-vapor flow is provided with a drain for removing condensed water.
- a drain for removing condensed water.
- such drain is in the valve placed on the duct feeding vapor to the tank.
- a further object of the present invention is a machine for preparing beverages, in particular coffee-based beverages, comprising a frothing device as above mentioned.
- the invention further concerns a process for frothing a beverage, particularly milk, by means of an above described device, comprising the steps of:
- the pressure sensor directly activates the valve delivering air and vapor to the milk.
- the contact of the pressure switch in series with the control of the electrovalve closes, thereby opening the electrovalve and allowing the tank to be connected to the above mentioned delivering means to deliver air and vapor to the beverage.
- the preset pressure value in the tank is comprised in the range between 0.6 bar and 1.8 bars, preferably between 0.7 bar and 1.4 bars, more preferably between 1.1 and 1.2 bars.
- the valve is opened (directly or through the control unit) thereby allowing the air-vapor mixture to reach the frothing means, that is to say the delivering means to deliver the air-vapor mixture to the milk or other beverage.
- the tank sizes are selected based on desired bulk; preferably the tank volume is at least 120 cc, and preferably between 120 cc and 260 cc. In some embodiments, the volume of the tank is comprised between 190 and 210 cc, preferably 200 cc. It was found that, at normal operating conditions of the machine and frothing device, these volumes allow the air-vapor mixture to be at an optimum temperature.
- the device further comprises a milk temperature sensor, preferably placed side by side with the air-vapor delivering wand.
- the sensor detects the milk temperature near the delivering wand and transmits the detected data to the control unit that, once the preset temperature is reached, stops the delivery of the frothing mixture, i.e. the air-vapor mixture, to the milk.
- the delivery of air and vapor mixture to the milk through the respective means, known as wand or spray nozzle is stopped when the milk reaches a temperature comprised in the range between 50° C. and 80° C., preferably between 55° C. and 65° C.
- the process provides a step of stopping the vapor delivery to the tank and keeping the air delivery; for example, it is possible to carry out such step at the end of the frothing step, in order to clean the ducts of the means delivering the air-vapor mixture.
- only air is delivered for a limited time, usually comprised between 0.1 s and 3 s.
- the invention also concerns a data medium as described herein. Many advantages are provided by the invention, compared with the known art.
- the air-vapor mixing is considerably improved by the tank that also allows to control the amount of the two fluids, thereby resulting in a better quality of frothed milk and a greater uniformity of minute bubbles forming the froth.
- the mixing tank allows to operate at constant pressure; in fact, even when the vapor boiler works a lot and, therefore, its operating pressure fluctuates among pressures ranging from 0.5-0.7 to 1.2-1.4 bars, the pressure obtained in the mixing tank is always the set one. This means that, even when the boiler pressure drops, the resulting froth obtained by the device of the present invention has unchanged quality.
- the vapor leaving the boiler to enter the mixing tank has temperature lower than 100° C. and pressure lower than 1 bar, then the required pressure is reached by a compensation with pressurized air, and the required milk temperature is reached by feeding the air-vapor mixture longer than in case of vapor at high temperatures.
- the condensation forming inside the hydraulic circuit during the resting step can be completely removed, thereby providing a further advantage.
- the three-way electrovalve positioned between the boiler and the tank allows to completely drain the water forming between the mixer and the boiler.
- the advantage of the device according to the invention is to be able to feed only vapor, if needed.
- several vapor outlets are connected to the vapor boiler; if a frothing circuit is provided, one of the outputs is dedicated thereto, while another output can be used to heat beverages only with vapor, without frothing effects.
- air is directly injected into the vapor boiler, then only a mix of vapor and air can be obtained from the boiler, so that it will be not possible to heat the milk without frothing it, or even to heat another beverage without frothing the latter.
- FIG. 1 is a scheme of a device according to the present invention.
- the frothing device 1 to froth a beverage, particularly milk comprises vapor producing means, for example a boiler 2 , and pressurized-air producing means 3 , in the shown embodiment these means include a pump 11 and, preferably, also a gicleur 19 upstream of the pump.

- the pressurized-air producing means 3 i.e. the pump 11
- the pressurized-air producing means 3 are connected with the tank 6 through a duct 12 ; on the duct 12 there can be intercepting means.
- the intercepting means comprise a flow regulator 13 for controlling the air flow rate to the tank.
- the invention provides for air and vapor being separately fed to the tank 6 ; in this way, the composition of the air-vapor mixture in the tank 6 and, accordingly, the composition of the air-vapor mixture delivered to the milk 18 to be frothed in the container 100 , can be both adjusted.
- the tank 6 is connected through a duct 7 to the delivering means 4 to deliver the air-vapor mixture to the milk 18 (or other beverage) held in the container 100 .
- the delivering means also known as “steam wand”, are known per se in the art and comprise a duct provided with a spray nozzle at the end thereof; as shown, the end is immersed into the milk 18 held in the container 100 .
- the frothed milk is at least partially removed from the container 100 in order to be fed to the user's cup; however, the invention is not limited to the shown application and any type of delivering means can deliver the mixture obtained in the tank 6 .
- the vapor-air mixture can be fed to frothing means comprising a frothing chamber (not shown) which is part of the beverage production machine.
- a frothing chamber is described in Patent EP 2534986 with reference to FIGS. 4 and 5 .
- intercepting means to intercept the air-vapor flow, for example a valve 8 , preferably a three-way electrovalve.
- the valve 8 is preferably provided with a draining way 17 acting so as to drain the water formed by vapor condensation when the device is at rest.
- the tank 6 is preferably provided with at least one pressure sensor 10 .
- the pressure sensor 10 can be a pressure transducer or a pressure switch. According to an embodiment, in both cases, the sensor generates a signal that is sent to a control unit 16 , generally a CPU, in order to control the operation of the device 1 .
- the pressure switch can instead be electrically connected, in series, to the electrovalve 8 , preferably by means of the on-off contact of the pressure switch; in this solution, the electrovalve is actuated by the pressure switch directly.
- the device 1 preferably comprises also a sensor 15 detecting the temperature of the milk 18 (or other beverage) during the frothing step thereof. A corresponding signal is generated and sent to the control unit 16 , in a known way.
- This type of temperature sensors are known, commercially available and used on some models of coffee machines.
- the control unit 16 is preferably connected at least to the valve 9 and the air pump 11 ; in the shown embodiment, the control unit, or CPU, 16 is also connected to the valve 8 controlling the feeding of the vapor-air mixture from the tank 6 to the frothing means 4 , to the pressure sensor 10 and to the temperature sensor 15 of the beverage.
- the control unit can be also connected with the flow regulator 13 in order to set the latter at a desired value depending on the beverage to be obtained.
- the process according to the invention provides for separately feeding air and vapor to the mixing tank 6 in order to obtain therein an air-vapor mixture; at the same time, the sensor 10 detects the pressure inside the tank 6 and a corresponding signal is sent either to the control unit 16 or the valve 8 .
- the CPU 16 can operate the intercepting means 8 , i.e. open the valve 8 , to connect the tank 6 with the delivering means 4 to deliver air and vapor to the milk 18 in the container 100 .
- the on-off contact of the pressure switch can be connected to the valve 8 in order to control the opening or closing thereof.
- the line connecting the pressure switch 10 and the valve 8 is referred to with the numeral 22 ; in a possible embodiment, this line is preferably present in place of the pressure switch 10 -CPU 16 -valve 8 connection.

- the sensor 10 can be a pressure switch sending an on-off signal when a suitable and preset pressure value is reached. As a result, the CPU 16 can actuate the valve 8 .
- the preset pressure value is comprised in the range between 0.6 bar and 1.8 bars, preferably between 0.7 bar and 1.4 bars, more preferably is about 1.1-1.2 bars.
- the control unit stops the air-vapor delivery on cue, or after a preset time or else when a preset temperature is reached.
- the air pump 11 can continue to feed air.

- the operator interface 21 connected to the CPU, comprises a cycle start button and, by pressing the same, the CPU 16 activates both the vapor electrovalve 9 and the air pump 11 , preferably at the same time; when the pressure inside the mixing tank 6 reaches the planned pressure P 1 , or when the pressure switch gives an on-off signal of reaching a pressure P 1 , the control unit 16 operates the opening of the valve 8 , which allows the flow of mixed air and vapor to reach the delivering means 4 , the end of which is immersed in the container 100 of the milk 18 . As a result, the milk frothing is obtained.
- the CPU 16 activates both the vapor electrovalve 9 and the air pump 11 , preferably at the same time.
- the electrovalve 8 is not activated via the CPU, because the contact of the pressure switch 10 is arrange in series to the control of the electrovalve 8 ; when the pressure inside the mixing tank 6 reaches the planned pressure P 1 , the pressure switch provides a pressure-reached on-off signal thereby activating the opening of valve 8 and allowing the flow of mixed air and vapor to reach the delivering means 4 , the end of which is immersed in the container 100 of the milk 18 , in order to froth milk.
- the temperature probe Beside the steam wand, the temperature probe, with a transducer connected to CPU, detects the milk temperature; when the planned temperature is reached, comprised in the range between 50° C. and 80° C., preferably between 55° C. and 65° C., the CPU 16 closes the valve 9 and the electrovalve 8 .
- the control unit, CPU in order to allow cleaning of the hydraulic circuit from the mixing tank 6 to the delivering means 4 at the end of the cycle, may keep the air pump active and the electrovalve 8 open for a few seconds.
